WorldWide Telescope, Microsoft’s galactic version of Google Earth, has been steadily increasing its fidelity ever since it launched in 2008, TechNewsDaily reports. Now, thanks to a new collaboration with NASA, WorldWide Telescope has produced the most detailed spherical image of the heavens to date, along with a new 3-D, true color map of the surface of Mars. As part of the new user experience in the WorldWide Telescope, Microsoft is also announcing a first of its kind: a high-resolution spherical TeraPixel sky map now available to viewers within the virtual telescope. The sky map is the largest and highest-quality spherical image of the sky currently available and was created from data provided by the Digitized Sky Survey, a collection of thousands of images taken over a period of 50 years by two ground-based survey telescopes. When those images are combined and processed, the TeraPixel image provides a complete, spherical, panoramic rendering of the night skies that, if displayed at full size, would require 50,000 high-definition televisions to view. The new high-quality image will give scientists with the ability to navigate through space dynamically to make their own discoveries…
